Graves ADC regarding Lethality build vs CDR & Deaths Dance

I feel like Youmuu's, Duskblade and Edge of night are providing much happier games and satisfying damage alongside 2 useful active items for teamfights & utility. I know Graves isn't played as adc in higher elo, I'm just enjoying him in lower tier while I climb up. Between thunderlords and the lethality build, it's been more promising than CDR and PD. I kind of cheapskate my "crit" by just leaving a brawlers gaunt in my inventory for that random10% backed by the lethality dmg-

thoughts?
